Print your own missiles

DefenseTech has an article on the potential of "portable factories" that print out custom-machined metal components for military use, but the real money-shot is the last paragraph: what happens when anyone can print a firearm or missile?

In the CNC world, proliferation becomes a matter of design, software, and materials, rather than finished systems. What happens when North Korea or Iran starts selling missiles as digital files rather than on ships which can be intercepted? When private designers and companies create designs which anyone can produce? Two words: Watch out.
